Fatness, In Perspective

Someone wants to be the world’s fattest woman.

And to do it, she’s going to consume 22,000 Calories per day, until she reaches 1,600 lb.

Breakfast: 6 x eggs scrambled, cooked in butter 468 cals. 1/2 pound bacon 1,168 cals, 4 x potatoes as hash browns 672 cals, 6 x pieces toast with butter 600 cals, 32 ounce cream shake 1,160 cals. Snacking 1 x bag of animal cookies 1,950 cals, 2litre bottle of soft drink 800 cals, 1 x 10.5 ounce bag of barbecue flavour crisps 1,650 cals, 3 x ham and cheese sandwiches 1,576 cals.
Lunch: 3 x beef, bean and green chilli burritos with 1 x cup of sour cream 1,453 cals. Salad (1 head lettuce, 1 cup cherry tomatoes, 1 cup carrots, 1 cucumber, 1/2 cup ranch dressing, bacon bits, 1 cup crumbled cheese, 1 cup chicken 1,479 cals.
Dinner: 12 x filled tacos + 1 x cup sour cream 4,906 cals, 2litre bottle of soda 800 cals, Dessert 8 x scoops vanilla ice cream 2,080 cals, 1 x small pan of brownies 1,200 cals.
Total: 21,962 calories

That’s ridiculous. So, in the spirit of my discovery earlier today that 500 Calories = 2000 kJ (2 MJ), I decided to see how much 20,000 Calories can do. For reference: 1 MJ = the kinetic energy of a 1-ton vehicle travelling at 100 mph. Source

I did a little Wolfram Alpha’ing.

So 20,000 Calories = ~90 MJ = [notables:]
…the rest energy of 1 microgram of mass. That may not sound like a lot, but that’s about 1016-1017 molecules, on average, of an average substance.
…an extra $3.74 of electricity (electricity is cheap!)
…26 kilowatt-hours
…the amount of energy that could light up a 60-watt lightbulb for 1500 hours, or a little over 2 months.
…the energy combusted by 2/3 of a gallon of gasoline (about 0.69 gallons). You can drive about 14 mi on a 20-mpg car with that much!

That’s a LOT of food… and a lot of energy for someone who’s on a wheelchair all day.
